  • Patent number: 5441499
    Abstract: The invention relates to a bipolar radio-frequency surgical instrument with a rigid tube shaft (11) and a working tip (12) which preferably has substantially the same cross-section as the adjoining part of the tube shaft (11) and is preferably centrally provided with at least one working electrode, such as a cutting electrode (13, 13") or a coagulating electrode (13') which can be energized with a radio-frequency voltage, and a neutral electrode (14) which preferably has a significantly larger surface. The working tip (12) is connected with the rigid tube shaft (11) near the distal end of the instrument in a hinged or flexible manner in such a way that the working tip (12) can be pivoted from a position which is axially aligned with the tube shaft (11) to a position which forms an angle relative to the tube shaft (11), and such that means (17, 18, 19) are provided to pivot and return the working tip (12).
